Methods and apparatuses for Orthogonal Frequency-Division Multiplexing (OFDM) communication of non-OFDM radio signals are disclosed. The non-OFDM radio signals are force-modulated into OFDM signals. In one example, a non-OFDM signal is received and is processed into an OFDM signal to produce a created OFDM signal. An actual OFDM signal is also received and is processed together with the created OFDM signal.

2. The method of claim 1 where the modulated first plurality of parallel streams of the transmitted radio signal comprises a WiFi signal as the OFDM signal and where the modulated second plurality of parallel streams of the transmitted radio signal comprises a Bluetooth signal as the non-OFDM signal.
3. The method of claim 1 where the channel comprises fifty-five subchannels.
This invention relates to wireless communication systems, specifically methods for optimizing data transmission through a communication channel. The problem addressed is improving transmission efficiency and reliability in environments with interference or signal degradation. The solution involves dividing a communication channel into multiple subchannels to enhance data throughput and reduce errors. The method uses a channel composed of fifty-five subchannels, each operating independently to transmit data segments. This division allows for parallel data transmission, increasing overall bandwidth utilization. The subchannels may employ different modulation schemes, error correction techniques, or frequency allocations to adapt to varying channel conditions. By dynamically adjusting subchannel parameters, the system can mitigate interference and optimize performance. The invention also includes mechanisms for monitoring subchannel performance and reallocating resources as needed. If a subchannel experiences degradation, data can be rerouted to other subchannels, ensuring continuous transmission. This adaptive approach improves reliability in dynamic environments, such as mobile networks or industrial wireless systems. The method is particularly useful in high-density communication scenarios where multiple devices share limited bandwidth. By subdividing the channel into fifty-five subchannels, the system achieves higher spectral efficiency and better error resilience compared to traditional single-channel approaches. This technique can be applied in 5G networks, IoT devices, or other wireless communication technologies requiring robust and efficient data transmission.

This invention relates to wireless communication systems, specifically improving data transmission efficiency and reliability in radio frequency (RF) communications. The problem addressed is the need for robust and high-throughput data transmission in environments with multipath interference and limited bandwidth. The invention describes a computing device configured to transmit and receive radio signals using a modulated plurality of parallel data streams. The device includes a transmitter that generates a radio signal divided into multiple parallel streams, each carrying a portion of the data. These streams are modulated to form an Orthogonal Frequency-Division Multiplexing (OFDM) signal, which distributes data across multiple subcarriers to mitigate interference and improve spectral efficiency. The device also includes a receiver that demodulates the OFDM signal to reconstruct the original data from the parallel streams. OFDM is a key feature, as it allows for high-speed data transmission by dividing the signal into orthogonal subcarriers, reducing inter-symbol interference and enhancing resilience to fading. The computing device may further include error correction mechanisms to ensure data integrity during transmission. The system is designed for applications requiring high data rates and reliable communication, such as wireless networks, IoT devices, and broadband communications. The invention aims to optimize bandwidth utilization while maintaining signal integrity in challenging RF environments.
